Abstract

Far-infrared radiation therapies are becoming more popular for blood circulation disorders, cardiovascular disease, skin diseases, inhibit cancer cell, etc replacing conventional operations. In this research, thermal characteristics of heating part in panel radiators, which is effective on the blood circulation disorders were experimentally analyzed. The heating line supplies heat energy to insulation coatings with heat flux of $150mW/m^2$ in normal status and as a result the coatings reached 20% of the heating line temperature. In other words, the insulation itself could increase surface temperature of heating plates by 20% and raise thermal time constant promote blood circulation effect. We also found that space arrangement of the heating lines was an important factor in designing heating parts and both coefficient of heat conduction and density of the heating plate should be also considered for superimpose of thermal diffusion.

혈액순환촉진, 심혈관계치료, 피부질환, 암세포억제 등의 의료분야에 원적외선 치료법이 광범위하게 활용되고 있다. 본 연구에서는 원적외선 치료에 효과적인 패널형 방사체의 발열부에 대한 열적 특성을 실험적으로 분석하였다. 발열선은 정상상태에서 절연피복에 $150mW/m^2$의 열유속으로 열에너지를 공급하여 절연피복은 발열선 온도의 20%에 도달하였다. 단열막 사용은 약 20%의 발열판 표면온도 증가효과가 있었으며 열시상수를 상승시켜 혈액순환촉진에 크게 기여하는 것으로 나타났다. 발열선의 배치간격이 발열부 설계에 중요한 인자이며 열확산의 중첩을 위해 발열판의 열전도계수와 밀도를 고려해야함을 알 수 있었다.
